Abstract

Thermal Performance of heat absorption system plays a significant role for the effective utilization of thermal energy form the sun. In this article, a water heating system with sun tracking concentrated solar collector was studied experimentally using zinc oxide (ZnO)-water nanofluid. The prime objective was to examine the ZnO nanofluid influence on the collectors’ thermal performance. For this, a parabolic type solar collector (PTSC) was fabricated and experiments were conducted in summer. The PTSC performance was measured initially by using water and then compared with ZnO nanofluid with 0.2 and 0.4 volume fractions. The solar radiation intensity at test location, working fluid temperature, ambient condition, and the discharge at the heating system were measured. The results showed the overall collector efficiency enhancement by 29% and 40%, respectively.
